Description & Features

Designed to support and protect primary seals in hydraulic assemblies, this Vickers Back Up Ring is a genuine Vickers by Danfoss/Eaton spare part intended for use in hydraulic system maintenance and rebuild applications. Back-up rings work alongside primary seals to prevent extrusion under pressure, helping to maintain seal integrity in demanding hydraulic environments.

Available in a variety of sizes, this component is suited for use in Vickers hydraulic equipment where OEM-compatible replacement parts are required. Sourcing a manufacturer-matched back-up ring helps ensure dimensional compatibility with existing seal grooves and housings.

Just want to make sure, this is for stopping leaks around the main seal, right?

Correct, these back-up rings are designed to support the primary seals and prevent them from squeezing out under high pressure. That keeps the whole hydraulic system sealed up tight.
